Here is one possible reason.
"The Government has recently announced that pre-election purdah before the next general election will begin on 30 March 2015, the same day as the dissolution of Parliament."
Election ?purdah? or the pre-election period - Commons Library Standard Note - UK Parliament
That is really really clever stuff. Every thing in the world of government starts on the 1st April and but we can't know about it because under the new electoral regime it is in the election campaign period. I hope you all got your tax coding already because next week you're screwed.
